For this case we have the following quadratic equation:
Where:
By definition, the discriminant of a quadratic equation is given by:
We have to:
Two different real roots
Two different complex roots
Two equal real roots
Substituting the values we have:
So, we have two different complex roots
Answer:
Two different complex roots
FIND LOT AREA:
Area = length * width
A= 18 feet * 45 feet
A= 810 feet squared
FIND # OF YARDS:
1 yard= 3 feet
Divide number of square feet by number of feet per yard.
Yards= 810 ÷ 3
Yards= 270
FIND PRICE OF SOD:
multiply number of yards by price per square yard.
Price= 270 yards * $12/yard
Price= $3,240
ANSWER: Cindy will pay $3,240 to cover the lot with sod.
Hope this helps! :)
